Final answer:
The subsidiary will recognize a capital gain of $10,000, which is the difference between the fair market value of the property received and the basis of the property in the liquidation.
Step-by-step explanation:
When a subsidiary is liquidated and its assets exceed its liabilities, including the basis of its property, the subsidiary will recognize a gain on the liquidation. In the scenario described, the subsidiary's property has a fair market value that is $10,000 greater than its basis in the hands of the subsidiary. Thus, the subsidiary will recognize a capital gain of $10,000 as a result of the liquidation, which is the difference between the fair market value received and the basis of the property.
